Calculation path

Average kW times hours gives delivered kWh, which is multiplied by the entered generator-specific fuel intensity.

Calculation path

Fuel litres = average electrical load kW x running hours x litres per kWh.

What you provide

What you provide

  • Average electrical load: Average real power supplied during the run.
  • Generator running hours: Total operating time in the modeled period.
  • Specific fuel consumption: Fuel litres required per electrical kWh near the modeled load.
  • Fuel price: Entered price for one litre of generator fuel.

What you receive

What you receive

  • Estimated fuel litres
  • Estimated fuel cost
  • Electrical energy and hourly fuel rate

Use boundary

Choose the maximum decimal places shown. This does not increase source accuracy.

Use a manufacturer load curve; idle burn, startup, derating, maintenance, fuel quality, and auxiliary loads vary.
